Time is divided into discrete time steps: discrete time steps

The concept of time.The recent time (existing time) is called (t), the next time step as (t 1), (t)I the preceding one as (t − 1).

All other time steps are called analogously. If in the following chapters several mathematical

Variables (e.g. netj or oi) refer to a certain point in time, the notation will be,

for example, netj(t − 1) or oi(t). From a biological point of view this is, of course, not very plausible (in the human brain a neuron does not wait for anotherone), but it significantly simplifies the implementation.
